All 3 of ours like grass, and we grow it for them. Oats is the best, and 5 lbs can be bought from a feed store for less than a couple of bucks, and a half cup in an 8" cake pan with holes punched for drainage and an inch of potting soil beneath the seeds (spread evenly) and an inch over them, and 4 or 5 days will see it big enough for them to pig out on. Dont let it get too dry, keep it sort of moist and it grows better. Tip: As soon as it starts sprouting, start another pan, because our guys really tear it up.
